Torque Wrench
HOW TO USE
A. Balancing wrench in hand with graduations visible with the marked arrow Elementary Scale up
then unlock knurled handle by turning lock nut counter clockwise.
B. Set amount of torque required by turning knurled handle to read exact
amount on case graduations.
EXAMPLE: 20Nm
1. Turn knurled handle until the zero graduation on the bevel edge of
the knurled handle is lined up with the vertical mark on the case and
is even with the 19Nm graduation.
2. Turn knurled handle clockwise until 1,0Nm graduation on the level
edge of the handle is in line with the vertical line on the case.
3. Lock handle securely by turning lock nut clockwise, and now wrench
is set at 20Nm which is ready to use .
C. lnstall the proper socket or attachmant to the square drive and apply to
nut or ball and pull handle until you feel and / or hear wrench click.
Release pull and wrench automatically resets for next operation.
Do not continue to pull after wrench releases. Use special care at low
torque settings that will pull stop when wrench clicks.
CAUTION
1. If wrench has not been used or has been in storage for some time, operate it several times at a
low torque setting which permits special internal lubricant to re-coat internaI working parts.
2. When wrench is not in use, keep doing adjustment at lowest torque setting.
3. Do not turn handle below lowest torque setting.
4. Do not continue pulling on the wrench after pre-set torque has been reached and the wrench has
been released. Pressure must be taken off the handle and the wrench allowed to automatically
reset itself, continuing to apply pressure after the wrench has been released, will result in damage
to the part being torque by applying more than the specified amount of torque.
5. Tool is rugged and designed for shop use, but is also a precision measuring instrument and
should be treated as such.
6. Clean wrench by wiping .Do not immerse in any type of cleaner which may affect special high
pressure lube with which the wrench is packed at the factory.
7. This torque wrench was calibrated and tested before leaving the factory and is accurate to ±4%.
8. The wrench is only suitable for measuring torque 5 to 25 Nm
This is a precisions measuring instrument.
Calibration and servicing must be done regularly and is the owner responsibility.
